SPECIFIGATION forming part of Letters latent No. 491,336, dated February7, 1893.

To @ZZ when?, it. may concern.-

Be it known that we, THOMAS A. CLOUGH and THOMAS J. BIGGER, bothcitizens of the United States, and residents of Philadelphia,Pennsylvania,haveinvented certain Improvements in Dyeing-Machines, ofwhich the following is a specification.

The object of our invention is to construct an improved rotary dyeingmachine in which the liquor will not raise and overliow the edge of thetank, owing to the continuons rotary motion of the yarn carrier, and atthe sanne time to more thoroughly agitate and :nix the liquor and dyeand all parts of the yarn alike, and to prevent the tangling of the yarnon the reels in the machine.

In the accompanying drawings:-l1`igure l, is a plan view of our improveddyeing inachine; Fig. 2, is a section on the line 1 2, Fig. l; Fig. 3,is a side View looking in the direction of the arrow, Fig. l; and Figs.e and 5, are side and sectional views respectively of the shittingwheel.

In rotary dyeing machines as now constructed the great trouble is inpreventing the water whirling as the yarn travels in a circular path inthe machine and overflowing the sides, and consequently the machine hasto be speeded very slow, and oftentimes devices are placed in the tankto prevent this movement of the liquid, and we also find that in rotarydyeing machines there is another great objection, that is, the tanglingof the yarn, owing tothe 'fact that the carriers are turned only oneway.

The machine illustrated in the accompanying drawings is an improvementon the ina` chine for which Letters Patent were applied for by Thomas A.Clough on April 19, 1889, Serial No. 307,652, therefore we will describethe tank portion of the machine briefly.

A is a cylindrical tank, and projecting from the bottom of this tank isa standard B through which passes the vertical shaft C carrying at itsupper end a clutch c engaging with a clutch h on the carrying frame D.This carrying traine has a series of open boxes at its periphery andnear its center, the outer boxes being carried by a ring connected tothe center by spindles. Adapted to these open boxes are the yarnspindles or sticks on which are suspended the hanks of yarn to be dyed,on the outer end ot cach stick is a pinion Which meshes with an annularrack on the edge of the tank A so that as the frame B turns, thespindles or sticks revolve in their bearings. IVe have shown an annularrack and pinion but friction wheels may be used in their place ifnecessary.

Suspended in each hank of .yarn is a loose roller which tends to keepthe hank straight while in the liquor.

The frame D can be readily lifted oit its bearings in the tub and asecond frame can be placed thereon, which has been previously chargedwith yarn to be dyed, so that it will be seen that while one frame is onthe tank, the dyed yarn on the other can be removed and the framerecharged, so as to be ready as soon as the yarn in the tank has beendyed.

Geared to the vertical shaft C is a horizontal shaft H on which is afast pulley I and two loose pulleys I I2, one on each side ot the fastpulley.

Situated above the pulleys is a belt shifting device consisting of alever .I pivoted at j to a bracket F on the side of the tank in thepresent instance; in one arm of this lever are two cam slots 7s 7c', tothe cam slot k is adapted a nin t' of a lever Krwhich is pivoted at gon?the ybracket F; this lever K has a loopt"` through which passes thedriving belt for turning the shaft in one direction, the belt beingadapted to the pulleys I I.

L is a shifter lever pivoted atl and provided With a pin Z adapted tothe slot 7e in the lever J. The lever L has a loop through which passesa belt which is adapted to the belt pulleys I I2 and which turns theshaft lI in the direction opposite that described in connection with thebelt adapted to the pulicys l and I. The arin j of the lever J isconnected to a rod M having a pin m thereon, preferably adjustable, thisrod is adapted to bearings in the bracket F.

On the shaft H is a pinion n which gears with a wheel n on a stud N,fast to the wheel n is a pinion n2 which meshes with a wheel n3 von astud N. An annular n ndercut groove p is formed in the face of the wheeln3 and adapted to this groove is a T-headed block p having a pin whichstrikes the pin m at certain points, as the pin fm, projects into thepath of the block. This block can be adjusted to any point on the wheeland two blocks may be used in some instances, which can be so adjustedin respect to each other and the pin m that the motion of the yarncarrier will be reversed at each single revolution of the carriage, asit will be understood that the block striking the pin m shifts thebelts, reversing the movement of the yarn carrier.

The operation of the machine is as followsz-Yarn is placed on the sticksand the sticks set in their respective places on the frame which is thenplaced in the tub so that a greater portion of the yarn is submerged inthe liquor. Motion is then applied to the vertical shaft through thegearing described above and the yarn carrier rotated in one direction,so that about five turns are required and then the block will strike thepin on the shifter and shift the belts so as to reverse the movement ofthe carrier at the same time, and the rotary motion of the hanks of theyarn will be reversed as will be readily understood on referring to thedrawings, thus it will be seen that all portions of the yarn will bethorougly dyed and the liquor thoroughly mixed, and owing to thereversing of the rotary motion at short intervals the liquor isprevented from swashing over the sides, consequently more liquor can becarried inthe tank than in rotary dyeing machines,and the speed of thecarrier can be increased.

Having thus described our invention we claim and desire to secure byLetters Patent:-

1. The combination in a machine for dyeing yarn, of the tank, thepivoted yarn carrying frame, with mechanism for driving said frame firstin one direction and then in the reverse direction, and means forautomatically shifting said mechanism, substantially as and for thepurpose set forth.

2. In a machine for dyeing yarn, the combination of the tank, a carryingframe, spindles mounted on said frame, mechanism substantially asdescribed for driving the spindles independently of the carrying frame,mechanism for driving the carrying frame first in one direction and thenin the opposite direction, mechanism for automatically shifting saiddriving mechanism, whereby the yarn is first carried through the liquidin one direction, while the yarn is moved on its spindle in onedirection, and then carried through the liquid in the reverse directionand the direction of the movement of the yarn on the spindles reversed,substantially as described.

3. The combination in a rotary yarn dyeing machine, of the tank, acarrying frame, spindles on said frame, said spindles being driven intheir bearings, from the periphery of the tank, a vertical shaftclutched to the carrying frame, mechanism for driving said shaft,reversing mechanism, and means for automatically acting on the reversingmechanism, whereby the carrying frame and yarn rollers are lirst turnedin one direction, and then reversed and turned in the oppositedirection, substantially as and for the purpose set forth.

4. The combination of the tank, the yarn carrier, spindles thereon onwhich the yarn is mounted, a vertical shaft passing through the centerof the tank, said shaft being clutched to the carrier, a horizontalshaft, fast and loose pulleys thereon, a shifting lever having cam slotstherein, looped levers having pins adapted to said cam slots, beltspassing through the loop of each of the looped levers, a rod connectedto the shifting levers and a projecting pin on said rod, a Wheel gearedto the horizontal shaft, and a pin on said Wheel adapted to strike thepin on the shifter' rod, to effect the reversal of the direction oftravel of the yarn carrier and the yarn, substantially as described.

5. The combination, in a yarn dyeing machine, of the tank, the yarncarrier, a driving shaft for the carrier, fast and loose pulleys on saidshaft, belt shifting lever, shifting rod connected thereto having aprojection, and a wheel geared to the driving shaft, with one or morepins adjustable on said wheel, whereby the reversing of the yarn carriermay be regulated, substantially as set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
